You transport Phosphorus in water you gonna get a heck of a big big surprise.

My son just did his chemistry report on Phosphorus - his mobile had a tube of toothpaste on it. Some phosphorus can not even be transported other than in water. Out of water well - you do not want to be anywhere near. Yet it is some toothpastes. Point well taken. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Thursday, March 06, 2008 1:38 PM To: [email protected] Subject: RE: Ordinary chemical plants? Toothpaste, uh, you'd die if you knew some of the stuff that goes into making some of our "non-hazardous" household products. Pharmaceuticals can use some highly toxic and flammable materials in the process if not in the actual commodity. Some of the chemicals used are used to cause certain reactions and are then discarded and not actually part of the end product but they are in the process. That's why you've got to know the process not just the end product. Some pharmaceuticals and food products have used acetone, hot oils, heat transfer fluids (class III's) above their flash points, ethylene oxide, and the list goes on. Again it's hard to make any assumptions when it comes to these kinds of facilities. So while a chemical plant could be OH2, they are kind of like unicorns. Craig L.

There could be chemical plants that are OH2. Say a plant manufacturing medical drugs. That would also be a chemical plant. If the processed material and products are non-hazardous, it could be OH2. Say a plant that manufactures toothpaste. I have no clue regarding materials involved. But if they are non-hazardous, could qualify for OH2. NFPA 45 for chemical laboratories classify labs OH1 and OH2 depending on the lab classification. The key is what are the material involved?

I'm glad to see others seem to be thinking along the same lines. This is the second design-build chemical facility project this year with no engineering or insurance company input and no company policies on fire protection other than 'code says we need sprinklers'. Let me pose this: if there is no such thing as an 'ordinary chemical plant' and they all require specific engineering analysis per NFPA 30, is NFPA doing a disservice by including this in 13? Anybody can read that statement and decide that a facility is an ordinary chemical plant and protect it as OH2 when it should be analyzed and could be a lot higher. Don't mean to dis the sprinkler bible, but this type of statement could have some unintended consequences.
